Anti-obesity potential of rare sugar d-psicose by regulating lipid metabolism in rats.
Food & Function, 2019d-Psicose is a new-generation sugar substitute with a low calorie count and can still offer the desirable sweetness. The objective of this study was to investigate the antiobesity potential of d-psicose and the possible mechanism using Wistar rats as the

Rational design of an improved transglucosylase for production of the rare sugar nigerose.
Chemical Communications, 2019The sucrose phosphorylase from Bifidobacterium adolescentis (BaSP) can be used as a transglucosylase for the production of rare sugars. We designed variants of BaSP for the efficient synthesis of nigerose from sucrose and glucose, thereby adding to the ...

Angewandte Chemie International Edition in English, 1969
AbstractThe use of new oxidation reagents, such as the Pfitzner‐Moffatt reagent, dimethyl sulfoxide‐acid anhydrides, and ruthenium tetroxide, has significantly improved the yields obtained on oxidation of a secondary hydroxyl group to a carbonyl group in suitably protected sugars.

Rare Sugars: Applications and Enzymatic Production
Journal of Biocatalysis & Biotransformation, 2012Rare Sugars: Applications and Enzymatic Production Rare sugars are monosaccharides and their derivatives rarely existing in nature. Of all hexoses and pentoses, only seven (D-glucose, D-galactose, D-mannose, D-fructose, D-xylose, D-ribose and L-arabinose) are present in significant amounts in nature.

3,6-Anhydro-l-galactose, a rare sugar from agar, a new anticariogenic sugar to replace xylitol.
Food Chemistry, 2017The significance for anticariogenic sugar substitutes is growing due to increasing demands for dietary sugars and rising concerns of dental caries. Xylitol is widely used as an anticariogenic sugar substitute, but the inhibitory effects of xylitol on Streptococcus mutans, the main cause of tooth decay, are exhibited only at high concentrations.

Adoligoses, Oligosaccharides of Rare Sugars from Adonis aleppica
Journal of Natural Products, 1995Five novel tri-, tetra-, and penta-saccharides named adoligoses A-E [1-5], consisting of rare didesoxy sugars and their 3-O-Me ethers, have been isolated from Adonis aleppica. Their structures were determined by dcims and nmr measurements. Full establishment of the proton spin-systems was based on 2D nmr data, spectral simulation procedures, and force ...

Catalytic oxidation of rare sugars over gold catalysts
Catal. Sci. Technol., 2013This minireview presents an overview on the recent developments for the heterogeneous catalytic aerobic oxidation of rare sugars over supported gold catalysts. The selective oxidation of several rare sugars; L-arabinose, D-galactose and D-lactose representing pentoses, hexoses and disaccharides, respectively, is reviewed. The critical evaluation of the
